If anyone has any objections, please let me know. ------------------ From: Cristian Ciocaltea [ Upstream commit 2d5661e6008ae1a1cd6df7cc844908fb8b982c58 ] According to the documentation, drivers are responsible for undoing at removal time all runtime PM changes done during probing. Hence, add the missing calls to pm_runtime_dont_use_autosuspend(), which are necessary for undoing pm_runtime_use_autosuspend(). Note this would have been handled implicitly by devm_pm_runtime_enable(), but there is a need to continue using pm_runtime_enable()/pm_runtime_disable() in order to ensure the runtime PM is disabled as soon as the remove() callback is entered.
